Vandex Super White is a cement based waterproofing slurry specifically designed for concrete waterproofing applications. It is mixed with water prior to application by brush or spray. Vandex Super White contains white cement.
When Vandex Super White is applied to a concrete surface, the active chemicals combine with the free lime and moisture present in the capilliary tract to form insoluble crystalline complexes. These crystals block the capillaries and minor shrinkage cracks in the concrete to prevent any further water ingress (even under pressure). However the Vandex Super White layer will still allow the passage of water vapour through the structure (i.e. the concrete will still be able to "breathe").
In addition to waterproofing the structure, Vandex Super White protects concrete against sea water, waste water, aggresive ground water and certain chemical solutions. Vandex Super White is approved for use in contact with potable water, and is therefore suitable for the treatment of water storage tanks, reservoirs, water towers, etc.
Vandex Super White can be applied to all structurally sound concrete - new or old. It may be applied to either the pressure or non-pressure concrete face (i.e. with or against water pressure).
Vandex Super White is not intended as a decorative material.
- New concrete (horizontal surfaces): Dry shake method is used to apply Vandex Super White directly from the container.
- Existing concrete and concrete vertical surfaces: One or two slurry coats.
